8

Considered a lucky number in many Asian cultures, the number eight is especially valued highly by Chinese. The Summer Olympics in Beijing happened on August 8, 2008 and started at 8.08pm (local time). There are areas in China where people would actually pay more money to get a telephone number with ‘8’ in it. Residences on eighth floor of buildings are also favoured.

4

This is considered as an unlucky number in parts of Asia such as China, Japan and even in our own abode. People take this superstition so seriously that there are many buildings in China that skip the fourth floor. Car buyers avoid picking out a license plate with the number four for fear of having their vehicle 'cursed'. This kind of fear is called Tetraphobia.

13

In Zoroastrianism, the 13th day of the year is seen as a day when evil might cause difficulties to people. In Christianity, there were 13 people at the Last Supper and Judas Iscariot, the man who betrayed Jesus, was the 13th man to join the table. Friday the 13th is also considered as unlucky in Western superstition.
